Ask a Teacher - Chemistry - Formulae and Equations - A Question from Zack

Student Name	Zack
Question	Could you please explain what GFM is when balancing equations. I understand its getting the RAM from the formula but which ones do you take it from?
Answer	The numbers used in balanced equations tell you the number of moles reacting and being produced. One mole is the same as the gram formula mass (GFM).
